In LaTeX, math equations are enclosed in dollar signs ($) to indicate that they are mathematical expressions. For inline math, a single dollar sign ($) is used, while for displayed math, double dollar signs ($$) are used. LaTeX provides a wide range of symbols and commands for writing math equations, making it a versatile tool for mathematical notation.

LaTeX offers a rich collection of symbols and notation for representing mathematical concepts. From basic arithmetic operations to complex mathematical functions, LaTeX provides a comprehensive set of tools for writing math equations.

In LaTeX, numbers and variables can be directly written using their respective characters. Basic arithmetic operations such as addition (+), subtraction (-), multiplication (*), and division (/) can be represented using their corresponding symbols.

Greek letters play a significant role in mathematical notation. In LaTeX, Greek letters can be easily incorporated using the backslash (\) followed by the name of the letter such as \alpha, \beta, \gamma, \phi, and \theta.

\alpha \beta \gamma \phi \theta

prints

Simple equations can be written in LaTeX using the basic arithmetic operations and mathematical symbols. For example, the equation y = mx + c can be represented as \(y = mx + c\), where the backslash followed by the parentheses indicates the beginning and end of the math expression.

Fractions in LaTeX can be written using the \frac{}{} command.

Example

\frac{x+1}{y-1}

prints

In LaTeX, powers can be represented using the caret (^) symbol.

Example

x^2

prints

Roots in LaTeX can be represented using the \sqrt[]{} command.

Example

\sqrt{4}

a_{n+1} = a_n + d

prints

The sum of a series in LaTeX can be represented using the \sum command.

Example

\sum_{i=1}^{n} a_i

prints

\sum_{k=1}^{n} k^2

prints

Integrals in LaTeX can be represented using the \int command.

Example

\int f(x) dx

prints

\int_{a}^{b} f(x) dx

prints

The binomial coefficient in LaTeX can be represented using the \binom{}{} command.

\binom{n}{k}

prints

\binom{n}{k} = \frac{n!}{k!(n-k)!}

prints

The symbols for for all and there exists in LaTeX can be represented using the \forall and \exists commands respectively.

Example

\forall x \in S, P(x)

prints

The equality and inequality operators in LaTeX can be represented using the symbols =, \neq, \leq, \geq, \approx, \equiv, etc.

Example

a = b, a \neq b, a \leq b, a \geq b, a \approx b, a \equiv b

prints

LaTeX provides the flexibility to handle complex mathematical expressions and nested equations by using appropriate syntax and structure. By utilizing the various commands and environments available in LaTeX, users can effectively represent intricate mathematical concepts and relationships.

Arrays in LaTeX can be used to represent matrices and vectors, align equations or create tables. They can be created using the array environment.

Example

\begin{array}{ccccc}
4x & + & y & = & 14 \\
7x & - & 4y & = & 8 \\
\end{array}

prints

\begin{array}{lcl}
f(x) & = & (a+b)^2 \\
& = & a^2+2ab+b^2 \\
\end{array}

prints

Matrices in LaTeX can be represented using the matrix environments such as matrix, pmatrix, bmatrix, etc.

Example

\begin{matrix}
2 & 9 \\
-7 & 4
\end{matrix}

prints

\begin{bmatrix}
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9
\end{bmatrix}

prints

\begin{equation*}
T_{i,j} =
\begin{pmatrix}
t_{1,1} & t_{1,2} & \cdots & t_{1,n} \\
t_{2,1} & t_{2,2} & \cdots & t_{2,n} \\
\vdots  & \vdots  & \ddots & \vdots  \\
t_{m,1} & t_{m,2} & \cdots & t_{m,n}
\end{pmatrix}
\end{equation*}

prints

Piecewise functions in LaTeX can be represented using the cases environment.

Example

f(x) =
\begin{cases}
0 & x < 0 \\
1 & x \geq 0
\end{cases}
